Bearclaw Valley Because he was a better boy, and more loved by the angels

Hadn't Evien been loyal to Ursus and the bear?

In a time before Aventus' life began, Evien was skeptical, and that could be what damned him. But for as long as Aventus had known the physician, the man was loyal. Why did the bears take Evien in exchange for Avicus, then, and not someone less devout? Because I told them to, he reminded himself, because father decreed it must be so. Still he believed that.

But Arielle, no, he would not sic the bears on Arielle. He knew that with a definitive certainty he could not put a finger on, but Aventus believed she would be great for Ursus. The boy sensed her determination and expected that she would do whatever it took for Ursus. Time would tell if his suspicion was correct.

You will be, he told her, and believed it fully. What do you bring to Ursus?
